Preface The third edition of Medical Terminology Simplified: A Programmed Learning Approach by Body Systems continues to reflect current trends and new approaches to teaching medical terminology. It remains a self-instructional book that can also be used in the traditional lecture and classroom environment. The organization and pedagogical devices of this text are designed to help you learn medical terminology easily and quickly. Use the teaching tools provided and you will find the more active you are in your studies, the better you learn and the more enjoyable the language of medicine becomes. All of the enhancements and new material in the third edition are constructed to make learning easier and at the same time improve retention. One of the most outstanding features of this edition is the extraordinary collection of all-new, visually outstanding, full-color illustrations. They are extremely useful as you learn the association of medical terms to anatomy, physiology, pathology, and medical treatments of the human body. All of the artwork is designed to present precise and well-composed depictions of medical terms in action. Full color in the figures enables you to see a true representation of the body system, pathological condition, and operative procedure. The most effective method of learning medical terminology is to understand the terms in their appropriate relationship to the human body. This includes having an understanding of anatomy and physiology, the types of treatments used to cure various disorders, and the disease processes of the human body—all of which are covered in this textbook. Another new feature of the third edition is the omission of possessive forms of all eponyms (names of diseases or disorders named after someone). For instance, we’ve changed Bowman’s capsule to Bowman capsule, Cushing’s syndrome to Cushing syndrome, and Parkinson’s disease to Parkinson disease. Many medical dictionaries, as well as the American Association for Medical Transcription and the American Medical Association, support these changes. The third edition also contains updated, comprehensive lists of medical abbreviations and their meanings, including a “do not use” abbreviations list mandated by the Joint Commission on Accreditation of Healthcare Organizations. In addition, all outdated medical terms have been replaced with the most recent, state-of-theart terms. To develop a contemporary teaching-and-learning package, the authors have implemented a number of insightful suggestions from numerous educators and students. Each body system chapter was updated to include: • Newly developed objectives at the beginning of each chapter help you understand what is essential in the chapter. The reviews and activities are linked directly to these objectives, so you can better evaluate your competency in each area. If you have not mastered a certain area, you might use the objectives as a study instrument to help you improve your understanding of the chapter. • Each chapter has a newly designed and more effective preview of word elements, along with a section review and competency verification to ensure maximum retention of medical terms. • Listen-and-Learn audio CD exercises will help you master the pronunciation, spelling, and meanings of selected medical terms. Learning the key terms is most effective when xv

used with the audio recordings that accompany the textbook. The audio recordings can also be used to begin developing transcription skills. • An enhanced pathology section, as well as a newly developed diagnostic and therapeutic section, will help you learn the clinical application of these new terms. • Flash card activities are included throughout the textbook. The cards present a quick and effective way to review medical word elements and their meanings. • Pronunciations are now included for medical records terminology, including many more pronunciations throughout each chapter. In addition, more than 200 terms from the Medical Records activities are now online. Visit the Listen and Learn Online! section for this book at www.fadavis.com/gylys/simplified to hear these terms.

Teaching and Learning Package A substantial number of supplemental teaching aids are available free of charge to instructors who adopt the third edition of Medical Terminology Simplified. These supplementary teaching materials are designed to aid students in their learning activities and to help instructors plan course work and presentations. After these supplements are integrated into course content, instructors will find that the various supplements provide a sound foundation for learning and help guarantee a full program of medical terminology excellence for all of your students.

Instructor’s Resource Disk The Instructor’s Resource Disk (IRD) features new and familiar teaching aids, created to make your teaching job easier and more effective than ever. The supplemental teaching aids on the IRD can be used in various educational settings- traditional classroom, distance learning, or independent studies. The IRD consists of an Activity Pack, three PowerPoint® presentations, and a Brownstone computerized test bank, a powerful test-generation program.

Activity Pack: Your Instructional Resource Kit The Activity Pack* provides instructional support for using the textbook. It contains an abundance of information and resources to help students retain what they have learned in a given chapter. It will also help you plan course work and presentations. These supplementary materials include: • Question Bank. The questions and answers in this section are taken from the Brownstone Computerized Test Bank found elsewhere on the IRD. The multiple-choice questions here offer only a small sample of the more than 700 test items available in the Brownstone test bank. Besides multiple-choice questions, the test bank also includes short answer and vocabulary questions. These items are available for every chapter in the text. A special feature of the multiple-choice questions is that they emulate the testing format used on many allied health national board examinations. This helps your students become better qualified to answer those types of questions. • Anatomical Illustrations. This new feature for each body system will help your students reinforce their understanding of anatomical structures introduced in the chapter. A template is provided for each illustration so you can use the illustration as a review exercise or testing device. • Suggested Course Outlines. Course outlines are included to help you determine a comfortable pace and plan the best method of covering the material presented. • Practical, Clinical, and Research Activities. A variety of newly-developed practical, clinical, and research application activities are included in this edition.

grate a clinical connection as a solid reinforcement of content. Feel free to select activities you deem suitable for your course and decide whether an activity is to be completed independently, with peers, or as a group project. The clinical connection exercises help your students understand how medical terms are used in clinical discussions. The practical application activities reinforce the spelling, pronunciation, and application of medical terminology in chart notes. Last, the research application activities will help your students understand the important role medical terminology plays in medical research. Included in this section are research projects related to the health-care industry. Your students will have an opportunity to hone their research skills by completing oral or written projects. These projects are also useful as an introductory element for exploring and then becoming members of professional organizations. A class visit to a meeting of a professional organization’s local chapter can help students understand the significance of developing research skills and how they affect the profession. An evaluation template for research projects can be found in the Activity Pack. • Community and Internet Resources. This section contains updated and expanded resources that offer a rich supply of technical journals, community organizations, and Internet resources to supplement classroom, internet, and oral and written projects. • Supplemental Medical Record Activities. In addition to updating the medical record activities from the previous edition, we’ve added supplemental activities for each of body system chapter. As in the textbook, these medical record activities use common clinical scenarios to show how medical terminology is used in the clinical area to document patient care. Activities for terminology, pronunciation, and medical record analyses are provided for each medical record, along with an answer key (in the Activity Pack). In addition, each medical record focuses on a specific medical specialty. These records can be used for group activities, oral reports, medical coding activities, or individual assignments. The medical records are designed to reinforce and enhance terminology presented in the textbook. • Crossword Puzzles. These fun, educational activities are included for each body system chapter. They’re designed to reinforce material covered in the chapter and can be used individually or in a group activity. They can also be used to provide extra credit or “just for fun.” An answer key is included for each puzzle. • Terminology Answer Keys. In response to requests we’ve received from instructors like you, this section provides the answers to the Terminology activities in the medical records sections of the textbook. This added feature provides instructional support in using the textbook and assists the instructor in correcting terminology assignments. • Master Transparencies. The transparency pages offer large, clear, black-and-white medical illustrations from selected figures in the text and have been chosen for their value as a testing device in reinforcing lecture information. They are perfect for making overhead transparencies or anatomical test questions and are provided for each body system.

PowerPoint Presentations This edition of Simplified contains not one but three PowerPoint presentations for your use: • Lecture Notes provides an outline-based presentation for each body system chapter. It consists of a chapter overview, the main functions and structures of the body system, and selected pathology, vocabulary, and procedures for each. Full-color illustrations from the textbook are included. • Illus-Station contains most illustrations from the text, with one illustration per slide. • Med TERMinator is an interactive presentation in which key terms from a chapter swoop into view each time the presenter clicks the mouse. You can ask students to say

1 Introduction to Programmed Learning and Medical Word Building O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Learn medical terminology by using the programmed learning technique. ■ Identify and define the four elements that are used to build medical words. ■ Analyze and define the various parts of a medical term. ■ Apply the rules learned in this chapter to pronounce medical words correctly. ■ Apply the rules learned in this chapter to write the singular and plural forms of medical words.

Instructions In the first few pages, you will learn the most efficient use of this self-instructional programmed learning approach. First remove the sliding card and cover the left-hand answer column with it. 1–1 This text is designed to help you learn medical terminology effectively. The principal technique used throughout the book is known as programmed learning, which consists of a series of teaching units called frames. Each frame presents information and calls for an answer on your part. When you complete a sentence by writing an answer on the blank line, you are learning information by using the programmed learning technique. A frame consists of a block of information and a blank line. The purpose answer

Medical Word Elements A medical word consists of some or all of the following elements: word root, combining form, suffix, and prefix. How you combine these elements and whether all or some of them are present in a medical word determine the meaning of a word. The purpose of this chapter is to help you learn to identify these elements and use them to form medical terms.

Pronouncing medical words correctly in a clinical setting is crucial because mispronunciations can result in incorrect medical interpretations and treatments. In addition, misspelled terms in a medical report may become a legal issue. Learning how to pronounce and spell medical terms is a matter of practice. To familiarize yourself with medical words, make it a habit to pronounce a word aloud each time you see the pronunciation listed. Also, use the audio CDROM, Listen and Learn, to hear pronunciations of terms in the Listen and Learn sections (beginning in Chapter 3) of this book.

Plural Suffixes Because many medical words have Greek or Latin origins, there are a few unusual rules you need to learn to change a singular word into its plural form. When you begin learning these rules, you will find that they are easy to apply. You also will find that some English word endings have been adopted for commonly used medical terms. When a word changes from a singular to a plural form, the suffix of the word is the part that changes. A summary of the rules for changing a singular word into its plural form is located on the inside back cover of this book.

2 Body Structure O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ List and describe the basic structural units of the body. ■ Describe the anatomic position. ■ Locate the body cavities and abdominopelvic regions of the body. ■ Describe terms related to position, direction, and planes of the body and their applications during

radiographic examinations. ■ Describe some common types of diagnostic procedures. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM

exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames and reviews.

The human body consists of several levels of structure and function (see Figure 2–1). Each higher level incorporates the structures and functions of the previous level. The cellular level is the smallest structural and functional unit of the body. Groups of cells that perform a specialized function form the tissue layer. Groups of tissue that perform a specific function form the organ level, and groups of organs that are interconnected or that have similar or interrelated functions form the system level. Finally, the collection of body systems makes up the most complex level, the organism level—a human being.

Organization of the Body Cellular Level 2–1 Cells are the smallest living units of structure and function in the human body. Every tissue and organ in the body is composed of cells. Review the illustration depicting the cellular level in Figure 2–1. Note the darkened area in the center, the nucleus, which is the control center of the cell and is responsible for reproduction. This spherical unit contains genetic codes for maintaining life systems of the organism and for issuing commands for growth and reproduction. nucle/o

2–15 Directional terms are commonly used in radiology to describe the direction of the x-ray beam from its source and its point of exit. In an anter/o/poster/ior projection, the beam enters the body anteriorly and exits posteriorly. A poster/o/anter/ior projection indicates that the beam enters the body posterior, anterior po˘s-TE-re- -or, a˘n-TI˘R-e- -or

The stomach is on the

side of the body.

The shoulder blades are on the

side of the body.

2–17 Whereas the term inferior in the English language refers to something of little or less importance, when used in a medical report, it designates a position or direction meaning lower or below. Combine infer/o (lower, below)  -ior (pertaining to, relating to) to form a directional term that literally means pertaining to lower or below. /

infer/ior ˘ı n-FE-re- -or

.

2–18 In medical terms, the prefix super- designates an upper position. When you say “the head is superior to the stomach,” you mean it is located above the stomach. When you say “the eyes are superior to the mouth,” you mean they are located

above

the mouth.

2–19 The word element later/o means side, to one side. A radiographic projection that enters through the left or right side of the body is referred to as a later/al projection. The term later/al position refers to the

side

(of the body).

Review the three basic rules for building medical words. Rule 1: A word root links a suffix that begins with a vowel. A L E R T

Rule 2: A combining form (root  o) links a suffix that begins with a consonant. Rule 3: A combining form (root  o) links a root to another root to form a compound word. This holds true even if the next root begins with a vowel.

Body Planes To visualize the structural arrangements of various organs, the body may be sectioned (cut) according to planes of reference. The three major planes are the frontal, median, and horizontal planes as shown in Figure 2–2. In addition, body cavities as shown in Figure 2–3 contain internal organs and are used as a point of reference to locate structures within body cavities.

2–33 Review Figures 2–2 and 2–3 carefully before proceeding with the next frame. You may refer to the two figures to complete the following frames. 2–34 A body plane is an imaginary flat surface that divides the body into two sections. Different planes divide the body into different sections, such as front and back, left side and right side, and top and bottom. These planes serve as points of reference for describing the direction from which the body is being observed. The planes are particularly useful to describe views in which radiographic images are taken. An imaginary flat surface that divides the body into two sections is a body plane

Recall the term super/ior. It is a point of reference that refers to a structure above or oriented toward a higher place. For example, the head is superior to the heart. Infer/ior is a point of reference that refers to a structure situated below or oriented toward a lower place. For example, the feet are inferior to the legs. Because the head is located superior to the heart, the heart is located to the head; because the feet are located inferior to , the legs, the legs are located

to the feet.

2–40 Many different transverse planes exist at every possible level of the body from head to foot. A trans/verse section is also called a crosssectional plane. Some radiographic imaging devices produce cross-sectional images. Cross-sectioning of the body or of an organ along different planes results in different views.

2–48 Let us continue to learn about the body cavities as you read and locate them in Figure 2–3. The (1) thoracic cavity contains the heart and lungs. The (2) abdominopelvic cavity contains organs of the reproductive and digestive systems and includes two subcavities, the (3) abdominal and (4) pelvic cavities. This subdivision is useful because of the different types of organs present in each (reproductive versus digestive). Because there is no dividing wall between them, they are actually one large cavity, the abdominopelvic cavity. 2–49 Use the terms superior and inferior to describe locations, or positions, of body cavities. superior soo-PE-re- -or

Abdominopelvic Quadrants 2–54 Because the abdominopelvic cavity is a large area and contains many organs, it is useful to divide it into smaller sections. One method divides the abdominopelvic cavity into quadrants. A second method divides the abdominopelvic cavity into regions. Physicians and health care professionals use both of these regional divisions as a point of reference. The larger division of the abdominopelvic cavity consists of four quadrants: right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ). Locate these quadrants in Figure 2–4A.

2–55 When you have located and reviewed the quadrants, determine the meaning of the following abbreviations right upper quadrant

Abdominopelvic Regions 2–59 Whereas larger sections of the abdominopelvic cavity are divided into four quadrants, the smaller sections are divided into nine regions, each of which corresponds to a region near a specific point in the body. As with quadrants, body region designation also is used to describe the location of internal organs and the origin of pain. Review Figure 2–4B to see the location of various organs within these regions.

˘ S-ko- -pe- ): visual examination of the interior of organs and cavities with a specialized endoscopy (e˘n-DO lighted instrument called an endoscope. Endoscopy also can be used to obtain tissue samples for cytological and histological examination (biopsy), to perform surgery, and to follow the course of a disease, as in the assessment of the healing of gastric and duodenal ulcers. The cavity or organ examined dictates the name of the endoscopic procedure (see Figure 2–6). A camera or video recorder frequently is used during this procedure to provide a permanent record.

˘ S-ko- -pe- ): radiographic procedure that uses a fluorescent screen instead of a photofluoroscopy (floo-or-O graphic plate to produce a visual image from x-rays that pass through the patient. The technique offers continuous imaging of the motion of internal structures and immediate serial images. Fluoroscopy is invaluable in diagnostic and clinical procedures. It permits the radiographer to observe organs, such as the digestive tract and heart, in motion. It also is used during biopsy surgery, nasogastric tube placement, and catheter insertion during angiography. ˘ T-ı˘c RE ˘ Z-e˘n-a˘ns ˘IM-ı˘j-ı˘ng): radiographic technique that uses electromagnetic resonance imaging (ma˘g-NE magnetic energy to produce multiplanar cross-sectional images of the body. Magnetic resonance imaging (MRI) does not require a contrast medium, but one may be used to enhance internal structure visualization (see Figure 2–5E). MRI is regarded as superior to CT for most central nervous system abnormalities, particularly abnormalities of the brainstem and spinal cord, and musculoskeletal and pelvic area abnormalities. -

nuclear scan (NU-kle- -a˘r): diagnostic technique that produces an image by recording the concentration of a radiopharmaceutical (a radioactive substance known as a radionuclide combined with another chemical). The radiopharmaceutical is introduced into the body (ingested, inhaled, or injected) and specifically drawn to the area under study. A scanning device detects the shape, size, location, and function of the organ or structure under study. It provides information about the structure and the function of an organ or system. There are a variety of nuclear scans, such as bone scans, liver scans, and brain scans (see Figure 2–5C).

˘ Z-ı˘-tro˘n e- -MI˘SH-u ˘ G-ra˘-fe- ): radiographic technique that compositron emission tomography (PO ˘ n to- -MO bines computed tomography with the use of radiopharmaceuticals. Positron emission tomography (PET) produces a cross-sectional (transverse) image of the dispersement of radioactivity (through emission of positrons) in a section of the body to reveal the areas where the radiopharmaceutical is being metabolized and where there is a deficiency in metabolism. PET is a type of nuclear scan used to diagnose disorders that involve metabolic processes. It can aid in the diagnosis of neurological disorders, such as brain tumors, epilepsy, stroke, Alzheimer disease, and abdominal and pulmonary disorders (see Figure 2–5F). ˘ G-ra˘-fe- ): production of captured shadow images on photographic film through the radiography (ra- -de- -O action of ionizing radiation passing through the body from an external source. Soft body tissues, such as the stomach or liver, appear black or gray on the radiograph; dense body tissues, such as bone, appear white on the radiograph, making it useful in diagnosing fractures. Figure 2–5A is a chest radiograph showing widening of the mediastinum. -

radiopharmaceutical (ra- -de- -o- -fa˘rm-a˘-SU-tı˘-ka˘l): drug that contains a radioactive substance that travels to an area or a specific organ that will be scanned. Kinds of radiopharmaceuticals include diagnostic, research, and therapeutic. scan: technique for carefully studying an area, organ, or system of the body by recording and displaying an image of the area. A concentration of a radioactive substance that has an affinity for a specific tissue may be administered intravenously to enhance the image. The liver, brain, and thyroid can be examined; tumors can be located; and function can be evaluated by various scanning techniques. -

˘ G-ra˘-fe- ): radiographic technique that produces a film representing a detailed crosstomography (to- -MO section of tissue structure at a predetermined depth. Tomography is a valuable diagnostic tool for discovering and identifying space-occupying lesions, such as those found in the liver, brain, pancreas, and gallbladder. Various types of tomography include computed tomography (CT), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). ˘ G-ra˘-fe- ): imaging technique that uses high-frequency sound waves (ultraultrasonography (u ˘ l-tra˘-so˘n-O sound) that bounce off body tissues and are recorded to produce an image of an internal organ or tissue. Ultrasonic echoes are recorded and interpreted by a computer, which produces a detailed image of the organ or tissue being evaluated. In contrast to other imaging techniques, ultrasound (US) does not use ionizing radiation (x-ray). It is used to diagnose fetal development and internal structures of the abdomen, brain, and heart and musculoskeletal disorders. The record produced by US is called a sonogram or echogram (see Figure 2–5B.)

Therapeutic -

anastomosis (a˘-na˘s-to- -MO-sı˘s): connection between two vessels; surgical joining of two ducts, blood vessels, or bowel segments to allow flow from one to the other (see Figure 2–7). cauterize (KAW-te˘r-ı-z): process of burning tissue by thermal heat, including steam, electricity, or another agent, such as laser or dry ice.

CHAPTER 3 • INTEGUMENTARY SYSTEM

The integumentary system consists of the skin and its accessory organs: the hair, nails, sebaceous glands, and sweat glands. The skin is the largest organ in the body and performs many vital functions: It shields the body against injuries, infection, dehydration, harmful ultraviolet rays, and toxic compounds. The skin is a protective interface between the body and the external environment. Beneath the skin’s surface is an intricate network of sensory receptors that register sensations of temperature, pain, and pressure. The millions of sensory receptors and a vascular network aid the functions of the entire body in maintaining homeostasis, a stable internal environment of the body (see Figure 3–1).

CHAPTER 3 • INTEGUMENTARY SYSTEM

Skin 3–1 The skin is considered an organ and is composed of two layers of tissue: the outer epidermis, which is visible to the naked eye, and the inner layer, the dermis. Identify and label the (1) epidermis and the (2) dermis in Figure 3–2. 3–2 The epi/derm/is forms the protective covering of the body and does not have a blood or nerve supply. It is dependent on the dermis for its network of capillaries for nourishment. As oxygen and nutrients flow out of the capillaries in the dermis, they pass through tissue fluid supplying nourishment to the deeper layers of the epidermis. When you talk about the outer layer of skin, you are referring to the /

3–6 Although the epidermis is composed of several layers, the (3) stratum corneum and the (4) basal layer are of greatest importance. The stratum corneum is composed of dead flat cells that lack a blood supply and sensory receptors. Its thickness is correlated with normal wear of the area it covers. Only the stratum germivatum is composed of living cells and includes a basal layer where new cells are formed. Label the two structures in Figure 3–2. 3–7 As new cells form in basal layer, they move toward the stratum corneum to replace the cells that have been sloughed off, they die and become filled with a hard protein material called keratin. The relatively waterproof characteristic of keratin prevents body fluids from evaporating and moisture from entering the body. The entire process by which a cell forms in the basal layers, rises to the surface, becomes keratinized, and sloughs off takes about 1 month. Check the basal layer in Figure 3–1 to see the single row of newly formed cells in the deepest layer of the epi/derm/is.

The production of melanin increases with exposure to strong ultraviolet light. This exposure creates a suntan that provides a protective barrier from the damaging effects of the sun. The number of melan/o/cytes is about the same in all races. Differences in skin color are attributed to production of melanin. In people with dark skin, melanocytes continuously produce large amounts of melanin. In people with light skin, melanocytes produce less melanin. The combining form melan/o refers to the color black.

MEDICAL RECORD ACTIVITIES

COMPOUND NEVUS Reading Practice pronunciation of medical terms by reading the following medical report aloud. A 29-year-old married white woman was referred for surgical treatment of a nevus of the right lower lip. The patient has had a small nevus located at the vermilion border of her lower lip all of her life, but recently it has enlarged and has become irritated with crusting and bleeding, through local trauma. The lesion was evaluated initially about 1 month ago during a period of trauma, but it could not be removed at that time because the patient had a prominent upper respiratory infection. Subsequently, there has been healing of the local inflammatory component, and the nevus is clear at this time. Examination reveals a brownish lesion with a flat, irregular border that is fairly circumscribed, measuring 0.5 cm in the greatest diameter and located just at the edge of the vermilion border on the right side of the lower lip. IMPRESSION: Compound nevus, lower lip, rule out melanoma.

Evaluation Review the medical record above to answer the following questions. 1. What is a nevus?

2. Locate the vermilion border on your lip. Where is it located?

3. Was the lesion limited to a certain area?

4. In the impression, the pathologist has ruled out melanoma. What does this mean?

5. Is a melanoma a dangerous condition? If so, explain why.

PSORIASIS Reading Practice pronunciation of medical terms by reading the following medical report aloud. Patient is a 24-year-old white woman who has experienced intermittent psoriasis since her early teens in various stages of severity. Since May, her condition has become more troublesome because of an increase of symptoms after being exposed to the sun. Her past history indicates she had chronic sinusitis of 3 years’ duration. Her Bartholin gland was excised in 20XX. She has had pruritus of the scalp and abdominal regions. There is no FH of psoriasis. An uncle has had diabetes mellitus since age 43. Patient has occasional abdominal pains accompanied by diaphoresis and/or syncope. PE showed the patient to have psoriatic involvement of the scalp, external ears, trunk, and, to a lesser degree, legs. There are many scattered erythematous (light ruby), thickened plaques covered by thick, yellowish white scales. A few areas on the legs and arms show multiple, sclerosed, brown macules and papules. DIAGNOSIS: 1. 2. 3. 4.

Psoriasis vulgaris. Multiple histiocytomas. Abdominal pain, by history. Rule out colitis, regional enteritis.

Evaluation Review the medical record above to answer the following questions. 1. What causes psoriasis?

2. On what parts of the body does psoriasis typically occur?

4 Respiratory System O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the respiratory system and discuss its primary functions. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the respiratory system. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

The respiratory system consists of the upper respiratory tract—the nose, pharynx, larynx, and trachea—and the lower respiratory tract—the left and the right primary bronchi, bronchioles, alveoli, and the lungs (see Figure 4–1). The main function of the respiratory system is to perform the pulmonary ventilation of the body. These structures, along with the cardiovascular system, transport oxygen and remove carbon dioxide (a waste product) from the cells of the body. This is accomplished by the events of respiration, exchanging oxygen and carbon dioxide between the environmental air and the blood circulating through the lungs. Secondary functions of the respiratory system include warming the air as it passes into the body and assisting in the speech function (providing air for the larynx and the vocal cords).

RESPIRATORY SYSTEM

Lower Respiratory Tract 4–31 Continue to label the structures in Figure 4–2, page 107, as you read the material in this frame. The (5) trachea (windpipe) is a cylindrical tube composed of smooth muscle embedded with a series of 16 to 20 C-shaped rings of cartilage. The trachea extends downward into the thoracic cavity, where it divides to form the (6) right and left primary bronchi (singular, bronchus). Each bronchus enters a lung and continues to subdivide into increasingly finer, smaller branches known as the (7) bronchioles. bronchus ˘ NG-ku BRO ˘s

The singular form of bronchi is

The smaller segments of the bronchus are called

4–32 The intricate network of air passages that supply the lungs looks like an inverted tree, with the trachea resembling the trunk. The term bronch/ial tree is often used to describe the series of respiratory tubes that branch into progressively narrower tubes as they extend into the lungs. Because each segment of the bronchial tree is an air passage that distributes the air throughout the lungs, surgical removal of any single segment is possible. Refer to Figure 4–1 to examine these structures. 4–33 The trachea’s cartilaginous rings provide the necessary rigidity to keep the air passage open at all times. The combining form chondr/o cartilage ˘ R-tı˘-lı˘j KA

4–35 On its way to the lungs, air passes from the larynx to the trachea, the airway commonly known as the windpipe. In a life-threatening situation, when trache/al obstruction causes cessation of breathing, a trache/o/stomy is performed through the neck into the trachea to gain access to an airway below a blockage (see Figure 4–3).

RESPIRATORY SYSTEM

4–39 Label the left lung in Figure 4–2 as you continue to read the material in this frame. Then review the position of the trachea to see how it branches into a right and left primary bronchus. Each primary bronchus (plural, bronchi) leads to a separate lung, the right and the (8) left lung. The structures of the bronchi and the alveoli are part of the lungs, which are the organs of respiration (act of breathing). 4–40

/

.

4–44 Structurally, each primary bronchus is similar to that of the trachea, but as they subdivide into finer branches, the amount of cartilage in the walls decreases and finally disappears in the bronchi/oles. As the cartilage diminishes, a layer of smooth muscle surrounding the tube becomes more prominent. The smooth muscles in the walls of the bronchioles can constrict or dilate these airways to maintain unobstructed air passages. The bronchi/oles eventually distribute air to the (9) alveoli (singular, alveolus), the small clusters of grapelike air sacs of the lungs. Each alveolus is surrounded by a network of microscopic (10) pulmonary capillaries. It is through these walls that an exchange of carbon dioxide (CO2) and oxygen (O2) takes place. Label the alveoli and pulmonary capillaries in Figure 4–2. 4–45 Macro/scopic structures are visible to the naked eye.

4–47 The entire process of gas exchange between the atmosphere and body cells is called respiration, which occurs in two processes. External respiration occurs each time we inhale (breathe in) air. This process results in a gas exchange (oxygen loading and carbon dioxide unloading) between the air-filled chambers of the lungs and the blood in the pulmonary capillaries (see Figure 4–2, structure 10). Internal (cellular) respiration is the exchange of gases (oxygen unloading and carbon dioxide loading) between the blood and body tissue cells. This occurs in body tissues when oxygen (carried in blood from the lungs to nourish the body’s cells) is exchanged for carbon dioxide. The carbon dioxide travels in the bloodstream to the lungs and is exhaled through the mouth or nose. You may have to read this frame a few times to understand the process of respiration. Nevertheless, see if you can differentiate between the two types of respiration. Gas exchange between the body and the outside environment is called external respiration

Pathological, Diagnostic, and Therapeutic Terms The following are additional terms related to the respiratory system. Recognizing and learning these terms will help you understand the connection between a pathological condition, its diagnosis, and the rationale behind the method of treatment selected for a particular disorder.

Pathological -

acidosis (a˘s-i-DO-sı˘s): excessive acidity of blood due to an accumulation of acids or an excessive loss of bicarbonate. Respiratory acidosis is caused by abnormally high levels of carbon dioxide (CO2) in the body. -

-

˘ S SI˘N-dro- m): respiratory insufficiency acute respiratory distress syndrome (a˘-KUT re˘s-PIR-a˘-to- -re- dı˘s-TRE marked by progressive hypoxia. This syndrome is due to severe inflammatory damage causing abnormal permeability of the alveolar-capillary membrane; also called adult respiratory distress syndrome (ARDS). The alveoli fill with fluid, which interferes with gas exchange.

PATHOLOGICAL, DIAGNOSTIC, AND THERAPEUTIC TERMS

127

˘ K-ta˘-sı˘s): collapse of lung tissue, preventing the respiratory exchange of oxygen and caratelectasis (a˘t-e˘-LE bon dioxide. Atelectasis can be caused by a variety of conditions, including obstruction of foreign bodies, excessive secretions, or pressure on the lung from a tumor. -

coryza (ko- -RI-za˘): acute inflammation of the nasal passages accompanied by profuse nasal discharge; also called a cold. ˘ K-a˘l): adventitious lung sound heard on auscultation of the chest, produced by air passing crackle (KRA over retained airway secretions or the sudden opening of collapsed airways. A crackle may be heard on inspiration or expiration and is a discontinuous adventitious lung sound as opposed to a wheeze, which is continuous; formerly called rale. croup (croop): acute respiratory syndrome that occurs primarily in children and infants and is characterized by laryngeal obstruction and spasm, barking cough, and stridor. -

cystic fibrosis (SI˘S-tı˘k f -ı-BRO-sı˘s): inherited disease of the exocrine glands with production of thick mucus that causes severe congestion within the lungs and digestive systems. The average life expectancy of a person with cystic fibrosis (CF) is approximately 20 years. -

empyema (e˘m-pı--E-ma˘): pus in a body cavity, especially in the pleural cavity (pyothorax). Empyema is usually the result of a primary infection in the lungs. -

epiglottitis (e˘p-ı˘-glo˘t-I-tı˘s): in the acute form, epiglottitis is a severe, life-threatening infection of the epiglottis and surrounding area; occurs most often in children between ages 2 and 12. In the classic form, a sudden onset of fever, dysphagia, inspiratory stridor, and severe respiratory distress occurs that often requires intubation or tracheotomy to open the obstructed airway. ˘ K-sı˘s): hemorrhage from the nose; also called nosebleed. epistaxis (e˘p-ı˘-STA -

hypoxemia (hı--po˘ks-E-me- -a˘): deficiency of oxygen in the blood; usually a sign of respiratory impairment; also called anoxemia. ˘ KS-e- -a˘): deficiency of oxygen in the tissues; usually a sign of respiratory impairment; also hypoxia (hı--PO called anoxia. ˘ N-za˘): acute, contagious respiratory infection characterized by sudden onset of fever, influenza (ı˘n-floo-E chills, headache, and muscle pain. ˘ NG KA ˘ N-se˘r): pulmonary malignancy commonly attributable to cigarette smoking. lung cancer (LU Survival rates are low due to rapid metastasis and late detection. ˘ S-ı˘s): acute infectious disease characterized by a “whoop”-sounding cough. Immunization pertussis (pe˘r-TU of infants as part of the diphtheria and tetanus (DPT) vaccine prevents contraction; also called whooping cough. -

pleural effusion (PLOO-ra˘l e˘-FU-zhu ˘ n): abnormal presence of fluid in the pleural cavity. The fluid may contain blood (hemothorax), serum (hydrothorax), or pus (pyothorax). -

pneumothorax (nu- -mo- -THO-ra˘ks): collection of air in the pleural cavity, causing the complete or partial collapse of a lung Pneumothorax can occur with pulmonary disease (emphysema, lung cancer, or tuberculosis) when pulmonary lesions rupture near the pleural surface allowing communication between an alveolus or bronchus and the pleural cavity. It may also be the result of an open chest wound, or a perforation of the chest wall that permits the entrance of air (see Figure 4–7).

PAPILLARY CARCINOMA Reading Practice pronunciation of medical terms by reading the following medical report aloud. A 55-year-old white man was seen 2 years ago because of upper airway obstruction due to large polyps in the right nasal cavity. On examination, a large polypoid mass was observed to fill most of the right nasal cavity. The mass originated in the middle meatus. With the use of a nasal snare, polypectomy was performed to remove several sections. There was a slight hemorrhage. On the next day, a 4
3 cm oval soft mass was excised from beneath the left submaxillary region, with the patient under local anesthesia. The mass was just beneath the superficial fascia and appeared to be an enlarged lymph node unconnected with the nasal disease. The pathological diagnosis of the nasal growth was low-grade papillary carcinoma. The diagnosis of the lymph node was metastatic carcinoma. A chest film was taken that indicated the presence of pulmonary densities attributed to unresolved pneumonia. Also, a needle biopsy of the enlarged liver nodes yielded no results. After discharge from the hospital, the patient expired at home, and no necropsy was obtained.

5 Cardiovascular and Lymphatic Systems O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the cardiovascular system and discuss its primary functions. ■ Describe the lymphatic system and discuss its primary functions. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the cardiovascular and lym-

phatic systems. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

The cardiovascular (CV) system is composed of the heart, which is essentially a muscular pump, and an extensive network of tubes called blood vessels. The main purpose of the CV system, also called circulatory system, is to deliver oxygen, nutrients, and other essential substances to the cells of the body and to remove the waste products of cellular metabolism. Delivery and removal of these substances are achieved by a complex network of blood vessels: the arteries, capillaries, and veins—all of which are connected to the heart. Without a healthy CV system that provides adequate circulation, tissues are deprived of oxygen and nutrients. In addition, waste removal ceases. When this happens, an irreversible change in the cells takes place that may result in a person’s death. The CV system is vital for survival. Because the lymphatic system does not have a pump, it depends on the pumping action of the heart to circulate its substances (see Figure 5–1). The lymphatic system is composed of lymph nodes, lymph vessels, and lymph fluid. It is responsible for draining fluid from the tissues and returning it to the bloodstream.

CHAPTER 5 • CARDIOVASCULAR AND LYMPHATIC SYSTEMS

Cardiovascular System Walls of the Heart 5–1 The heart is a four-chambered muscular organ located in the mediastinum, the area of the chest between the lungs. Its primary purpose is to pump blood through the arteries, veins, and capillaries. The walls of the heart are composed of the: (1) endocardium, the (2) myocardium, and the (3) pericardium. Review the structures of the heart and label its three layers in Figure 5–2. 5–2 The endo/cardi/um, the inner membranous layer, lines the interior of the heart and the heart valves. The myocardium, the middle muscular layer, is composed of a special type of muscle arranged in such a way that the contraction of muscle bundles results in squeezing or wringing of the heart chambers to eject blood from the particular chambers. The peri/cardi/um, a fibrous sac, surrounds and encloses the entire heart. When we talk about the muscular layer of the heart, we are referring to the my/o/cardi/um ˘ R-de- -u mı--o- -KA ˘m peri/cardi/um ˘ R-de- -u pe˘r-ı˘-KA ˘m

CHAPTER 5 • CARDIOVASCULAR AND LYMPHATIC SYSTEMS

Circulation and Heart Structures 5–8 The circulatory system is frequently divided into the cardiovascular system, which consists of the heart and blood vessels, and the lymphatic system, which consists of lymph vessels, lymph nodes, and lymphoid organs (spleen, thymus, and tonsils). Review Figure 5–1 to see the interrelationship of the cardiovascular system with the lymphatic system. 5–9 Some of the main vessels associated with circulation are illustrated in Figure 5–2. Observe the locations and label the structures as you read the following material. The (4) aorta, the largest blood vessel in the body, is the main trunk of systemic circulation. It starts and arches out at the left ventricle. Deoxygenated blood enters the (5) right atrium via two large veins, the vena cavae (singular, vena cava). The (6) superior vena cava conveys blood from the upper portion of the body (head and arms); the (7) inferior vena cava conveys blood from the lower portion of the body (legs). 5–10 Blood in the veins except for pulmonary veins has a low oxygen content (deoxygenated) and a relatively high concentration of carbon dioxide. In contrast to the bright red color of the oxygenated blood in the arteries, deoxygenated blood has a dark blue to purplish color. deoxygenated de- -o˘k-sı˘-je˘n-A-te˘d

The term in this frame that means low oxygen content is

.

5–11 Label Figure 5–2 as you continue to identify and learn about the structures and functions of the circulatory system. The (8) pulmonary trunk is the only artery that carries deoxygenated blood. As deoxygenated blood is pumped from the right ventricle, it enters the pulmonary trunk. The pulmonary trunk runs diagonally upward, then divides abruptly to form the branches of the right and left pulmonary arteries. Each branch conveys deoxygenated blood to the lungs. The (9) right lung has three lobes; the (10) left lung has two lobes. Oxygen-rich blood returns to the heart via four pulmonary veins, which deposit the blood into the left atrium. There are two (11) right pulmonary veins and two (12) left pulmonary veins. Competency Verification: Check your labeling of Figure 5–2 in Appendix B, Answer Key, page 514.

5–12 Internally the heart is composed of four chambers. The upper chambers are the (1) right atrium (RA) and (2) left atrium (LA). The lower chambers are the (3) right ventricle (RV) and (4) left ventricle (LV). Locate and label the chambers of the heart in Figure 5–3. 5–13 atri/al A-tre- -a˘l

CHAPTER 5 • CARDIOVASCULAR AND LYMPHATIC SYSTEMS

Blood Flow Through the Heart 5–30 Although general circulatory information was discussed previously, this section covers in greater detail the specific structures involved in the flow of blood through the heart. The heart’s double pump serves two distinct circulations: pulmonary circulation, which is the short loop of blood vessels that runs from the heart to the lungs and back to the heart; systemic circulation routes blood through a long loop to all parts of the body before returning it to the heart. Continue to label Figure 5–3 as you read the following information. The right atrium receives oxygen-poor blood from all tissues except those of the lungs. The blood from the head and arms is delivered to the RA through the (6) superior vena cava (SVC). The blood from the legs and torso is delivered to the RA through the (7) inferior vena cava (IVC).

CARDIOVASCULAR SYSTEM

5–39 The ventricles are the pumping chambers of the heart. As the right ventricle contracts to pump oxygen-deficient blood through the (9) pulmonary valve into the pulmonary artery, the tri/cuspid valve remains closed, preventing a backflow of blood into the right atrium. When the blood passes through the main pulmonary artery, it branches into the (10) right pulmonary artery and the (10) left pulmonary artery. The pulmonary arteries carry the oxygen-deficient blood to the lungs. Label the structures introduced in this frame in Figure 5–3. 5–40 artery ˘ r-te˘r-eA

Heart Valves 5–71 Label Figure 5–4 as you read the material about the heart valves and their cusps, also called flaps. Four heart valves maintain the flow of blood in one direction through the heart. The (1) tricuspid valve and the (2) mitral valve are situated between the upper and lower chambers and are attached to the heart walls by fibrous strands called (3) chordae tendineae. The (4) pulmonary valve and the (5) aortic valve are located at the exits of the ventricles. Heart valves are composed of thin, fibrous cusps covered by a smooth membrane called endocardium reinforced by dense connective tissue. The aortic, pulmonary, and tricuspid valves contain (6) three cusps; the mitral valve contains (7) two cusps. The purpose of the cusps is to open and permit blood to flow through and seal shut to prevent backflow. The opening and closing of the cusps takes place with each heartbeat.

CHAPTER 5 • CARDIOVASCULAR AND LYMPHATIC SYSTEMS

Cardiac Cycle and Heart Sounds 5–84 The cardi/ac cycle refers to the events of one complete heartbeat. Each contraction, or systole, of the heart is followed by a period of relaxation, or diastole. This occurs 60 to 100 times per minute in the normal functioning heart. The normal period of heart contraction is called systole; the normal period diastole ˘ S-to- -ledı--A

The following summary provides a brief, general interpretation of an ECG. A more comprehensive explanation of ECG abnormalities is beyond the scope of this book. Refer to Figure 5–5 as you read the text that follows. A normal heart rhythm or sinus rhythm shows five waves or deflections on the ECG strip, which represent electrical changes as they spread through the heart. The deflections are known as the P, QRS, and T waves. The P wave, which represents the transmission of electrical impulses from the SA node, indicates atrial contraction. The QRS waves represent the electrical impulses through the bundle of His and the Purkinje fiber system and ventricular walls (during systole). The T wave represents the electrical recovery and relaxation of the ventricles (during diastole).

5–92 Although the heart itself generates the heartbeat, factors such as hormones, drugs, and nervous system stimulation also can influence the heart rate. To evaluate a patient’s heart rate, a physician may order an EKG, which is an abbreviation for /

Lymphatic System The lymphatic system consists of lymph, lymph vessels, many lymphoid tissue masses known as lymph nodes, and three organs—the tonsils, thymus, and spleen. All of these organs, including bone marrow, play an important role in the immune response. An important function of the lymphatic system is to drain excess fluid from the tissues, to return the tissue fluid back to the bloodstream, to protect the body against infectious disease and foreign invaders, and to maintain a healthy internal environment in the body. Lymph fluid originates from the blood. As certain constituents of blood plasma filtrate through the tiny capillaries into the spaces between cells, it becomes interstitial fluid. Most of the interstitial fluid is absorbed from the interstitial (or intercellular) spaces by thin-walled vessels called lymph capillaries. At this point, interstitial fluid becomes lymph and is passed through lymphatic tissue called lymph nodes. Eventually lymph reaches large lymph vessels in the upper chest and reenters the bloodstream (see Figure 5–1).

PATHOLOGICAL, DIAGNOSTIC, AND THERAPEUTIC TERMS

177

Pathological, Diagnostic, and Therapeutic Terms The following are additional terms related to the cardiovascular and lymphatic systems. Recognizing and learning these terms will help you understand the connection between a pathological condition, its diagnoses, and the rationale behind the method of treatment selected for a particular disorder.

Pathological Cardiovascular System ˘ N-u- -rı˘zm): localized dilation of the wall of a blood vessel, introducing the risk of a rupture. aneurysm (A An aneurysm may rupture, causing hemorrhage, or thrombi may form in the dilation and give rise to emboli that may obstruct smaller vessels (see Figure 5–7). arrhythmia (a˘-RI˘TH-me- -a˘): irregularity or loss of rhythm of the heartbeat; also called dysrhythmia. -

arteriosclerosis (a˘r-te- -re- -o- -skle- -RO-sı˘s): thickening, hardening, and loss of elasticity of arterial walls. Arteriosclerosis results in altered function of tissues and organs; also called hardening of the arteries. -

atherosclerosis (a˘th-e˘-ro- -skle- -RO-sı˘s): most common form of arteriosclerosis, caused by an accumulation of fatty substances within the walls of the arteries causing partial and eventually total occlusion (see Figure 5–6). bruit (brwe- ): soft blowing sound heard on auscultation caused by turbulent blood flow. -

˘ R-te˘r-e- ): abnormal condition that may affect the heart’s arteries coronary artery disease (KOR-o- -na˘-re- A and produce various pathological effects, especially the reduced flow of oxygen and nutrients to the myocardium (see Figure 5–6). The most common kind of coronary artery disease is coronary atherosclerosis, now the leading cause of death in the Western world. -

-

deep vein thrombosis (DEP va- n thro˘m-BO-sı˘s): formation of a blood clot in a deep vein of the body, occurring most frequently in the iliac and femoral veins. ˘ M-bo- -lu embolus (E ˘ s): mass of undissolved matter present in a blood or lymphatic vessel brought there by the blood or lymph current. Emboli may be solid, liquid, or gaseous. Occlusion of vessels from emboli usually results in the development of infarcts. -

fibrillation (f ˘ı -brı˘l-A-shu ˘ n): irregular, random contraction of heart fibers. Fibrillation commonly occurs in the atria or ventricles of the heart and is usually described by the part that is contracting abnormally, such as atrial fibrillation or ventricular fibrillation. heart failure: condition in which the heart cannot pump enough blood to meet the metabolic requirement of body tissues. Heart failure (HF) includes myocardial infarction, ischemic heart disease, and cardiomyopathy. It also may be caused by the dysfunction of organs other than the heart, especially the lungs, kidneys, and liver. The term heart failure (HF) is currently replacing the term congestive heart failure (CHF). ˘ N-shu hypertension (hı--pe˘r-TE ˘ n): consistently elevated blood pressure that is higher than normal causing damage to the blood vessels and ultimately the heart.

MYOCARDIAL INFARCTION (MI) Reading Practice pronunciation of medical terms by reading the following medical report aloud. A 70-year-old white woman was admitted to the hospital for evaluation of a syncopal episode. She states that most recently she has experienced generalized malaise, increased shortness of breath while at rest, and dyspnea followed by periods of apnea and syncope. Her past history includes recurrent episodes of thyroiditis, which led her to have a thyroidectomy 6 years ago while she was under the care of Dr. Knopp. At the time of surgery, the results of her EKG were interpreted as sinus tachycardia with nonspecific ST-T wave changes. The tachycardia was attributed to preoperative anxiety and thyroiditis. Postoperatively, under the direction of Dr. Knopp, the patient was treated with a daily dose of 50 mg of desiccated thyroid and has been symptom-free until this admission. On clinical examination, the patient’s radial pulse was found to be irregular, and the EKG showed uncontrolled atrial fibrillation with evidence of a recent myocardial infarction (MI).

Evaluation Review the medical record to answer the following questions. 1. What symptoms did the patient experience before admission to the hospital?

2. What was found during clinical examination?

3. What is the danger of atrial fibrillation?

4. Did the patient have prior history of heart problems? If so, describe them.

5. Was the patient’s prior heart problem related to her current one?

CARDIAC CATHETERIZATION Reading Practice pronunciation of medical terms by reading the following medical report aloud. PROCEDURE: The patient was prepared and draped in a sterile fashion and 20 mL of 1% lidocaine was infiltrated in the right groin. A No. 6 French Cordis right femoral arterial sheath was placed and a No. 6 French JL-5 and JR-4 catheter was used to engage the left and right coronary. A No. 6 French pigtail was used for left ventricular angiography. Angioplasty was made, and further dictation is under the angioplasty report. There were minor irregularities, with a maximal 25% stenosis just after the first diagonal. The remainder of the vessel was free of significant disease. A 0.014, high-torque, floppy, extra-support, exchange-length wire was used to cross the stenosis in the distal right coronary artery. A 3.5
20-mm Track star balloon was inflated in the right coronary artery in the distal portion. The initial stenosis was 50% to 75% with an ulcerated plaque, and the final stenosis was 20% with no significant clot seen in the region. The patient had significant ST elevations in the inferior leads and severe throat tightness and shortness of breath. This would resolve immediately with the inflation of the balloon. The catheters were removed, and the sheath was changed to a No. 8 French Arrow sheath. The patient will be on heparin over the next 12 hours. IMPRESSION: (1) Two-vessel coronary artery disease with a 75% obtuse marginal and a 75% right coronaryartery lesion; (2) normal left ventricular function; (3) successful angioplasty to right coronary artery with initial stenosis of 75% and a final stenosis of 20%.

Evaluation Review the medical record to answer the following questions. 1. What coronary arteries were under examination?

2. Which surgical procedure was used to clear the stenosis?

3. What symptoms did the patient exhibit before balloon inflation?

4. Why was the patient put on heparin?

cises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews,

and medical report evaluations.

The digestive system, also known as the gastrointestinal (GI) system, consists of a digestive tube called the GI tract, or alimentary canal. The GI system includes several accessory organs whose primary function is to break down food, prepare it for absorption, and eliminate waste substances. The GI tract, extending from the oral cavity (mouth) to the anus, varies in size and structure in several distinct regions. It terminates at the anus, where solid wastes are eliminated from the body by means of defecation (see Figure 6–1).

Small and Large Intestine 6–85 The small intestine is a continuation of the GI tract. It is where digestion of food is completed as nutrients are absorbed into the bloodstream through tiny, finger-like projections called villi. Any unabsorbed material is passed on to the large intestine to be excreted from the body. There are three parts of the small intestine: the (1) duodenum, the(2) jejunum, and the(3) ileum. Label these parts in Figure 6–3. 6–86

Here is a review of the parts of the small intestine.

Accessory Organs of Digestion: Liver, Gallbladder, and Pancreas 6–145

Label Figure 6–6 as you learn about the accessory organs of

digestion. Even though food does not pass through the (1) liver, (2) gallbladder, and (3) pancreas, these organs play a vital role in the proper digestion and absorption of nutrients. The gallbladder serves as a storage site for bile, which is produced by the liver. When bile is needed for digestion, the gallbladder releases it through ducts into the (4) duodenum through the (5) common bile duct. liver

CHAPTER 6 • DIGESTIVE SYSTEM

Pathological, Diagnostic, and Therapeutic Terms The following are additional terms related to the digestive system. Recognizing and learning these terms will help you understand the connection between a pathological condition, its diagnoses, and the rationale behind the method of treatment selected for a particular disorder.

Pathological -

appendicitis (a˘-pe˘n-dı˘-SI-tı˘s): inflammation of the appendix, usually acute and caused by blockage of the appendix that is followed by infection. When left untreated, it rapidly leads to perforation and peritonitis. Treatment for acute appendicitis is appendectomy within 48 hours of the first symptom. Any further delay in treatment results in rupture and peritonitis as fecal matter is released into the peritoneal cavity (see Figure 6–8).

Navel

Incision Appendix A. Diseased appendix

B. Incision site

C. Excision of diseased appendix

Appendectomy.

-

ascites (a˘-SI-te- z): abnormal accumulation of serous fluid in the abdomen. Ascites occurs when fluid drains out of the bloodstream and accumulates in the peritoneal cavity. It may be a symptom of inflammatory disorders in the abdomen, venous hypertension caused by liver disease, or heart failure. borborygmus (bo˘r-bo- -RI˘G-mu ˘ s): gurgling or rumbling sound heard over the large intestine, caused by gas moving through the intestines. -

cirrhosis (sı˘-RO-sı˘s): chronic liver disease characterized pathologically by destruction of liver cells that eventually leads to ineffective liver function and jaundice. ˘ N-ı˘k po˘l-e- -PO colonic polyposis (ko- -LO -sı˘s): polyps, which are small benign growths, that project from the mucous membrane of the colon. Polyps have the potential of becoming cancerous, so they are checked frequently or removed to detect any abnormalities at an early stage. Colonic polyps have a high likelihood of becoming colorectal cancer.

Crohn disease (kro- n): chronic inflammatory bowel disease, usually affects the ileum, but may affect any portion of the intestinal tract. It is distinguished from closely related bowel disorders by its inflammatory pattern, which tends to be patchy or segmented; also called regional colitis.

dysentery (DI˘S-e˘n-te˘r-e- ): term applied to many intestinal disorders, especially of the colon, characterized by inflammation of the mucous membrane, diarrhea, and abdominal cramps. fistula (FI˘S-tu- -la˘): abnormal passage from one organ to another, or from a hollow organ to the surface. An anal fistula is located near the anus and may open into the rectum. -

hematochezia (he˘m-a˘-to- -K E-ze- -a˘): passage of stools containing bright red blood. ˘ M-o- -royd): mass of enlarged, twisted varicose veins in the mucous membrane inside hemorrhoid (HE (internal) or just outside (external) the rectum; also known as piles. ˘ R-ne- -a˘): protrusion or projection of an organ or a part of an organ through the wall of the hernia (HE cavity that normally contains it (see Figure 6–10). ˘ M-a˘-to˘r-e- bou-a˘l): ulceration of mucosa of the colon. Ulcerative colitis inflammatory bowel disease (ı˘n-FLA and Crohn disease are forms of inflammatory bowel disease; also known as IBD. irritable bowel syndrome (I˘R-ı˘-ta˘-bl bou-a˘l SI˘N-dro- m): abnormal increase in the motility of the small and large intestines that generally is associated with emotional stress. No pathological lesions are found in the intestine. In diagnosing irritable bowel syndrome (IBS), other, more serious conditions, such as dysentery, lactose intolerance, and inflammatory bowel disease, must be ruled out because there is no organic disease present in IBS; also called spastic colon. jaundice (JAWN-dı˘s): yellow discoloration of the skin, mucous membranes, and sclerae of the eyes, caused by excessive levels of bilirubin in the blood (hyperbilirubinemia). ˘ L-ı˘p): small, tumor-like benign growth that projects from a mucous membrane surface. polyp (PO

polyposis (po˘l-e- -PO-sı˘s): general term for a condition in which polyps develop in the intestinal tract. ulcer (UL-se˘r): open sore or lesion of the skin or mucous membrane, accompanied by sloughing of inflamed necrotic tissue. An ulcer may be shallow, involving only the epidermis, or it may be deep, involving multiple layers of the skin. Some examples of ulcers are peptic ulcer, duodenal ulcer, and decubitus ulcer. ˘ L-vu- -lu volvulus (VO ˘ s): twisting of the bowel on itself, causing obstruction. Usually requires surgery to untwist the loop of bowel.

Diagnostic ˘ -re- -u ˘ N-e˘ -ma˘): radiographic examination of the rectum and colon after administrabarium enema (BA ˘m E tion of barium sulfate (radiopaque contrast medium) into the rectum. This procedure is used for diagnosis of obstructions, tumors, or other abnormalities, such as ulcerative colitis. ˘ -re- -u barium swallow (BA ˘ m): radiographic examination of the esophagus, stomach, and small intestine after oral administration of barium sulfate (radiopaque contrast medium). Structural abnormalities of the esophagus and vessels, such as esophageal varices, may be diagnosed by use of this technique; also called upper GI series.

˘ G-ra˘-f e- ): radiographic technique that uses a narrow computed tomography (CT) scan (ko˘m-PU-te˘d to- -MO beam of x-rays, which rotates in a full arc around the patient to image the body in cross-sectional slices. A scanner and detector send the images to a computer, which consolidates all of the data it receives from the multiple x-ray views (see Figure 2–5D). In the digestive system, CT scans are used to view the gallbladder, liver, bile ducts, and pancreas. CT scan is used to diagnose tumors, cysts, inflammation, abscesses, perforation, bleeding, and obstructions. A contrast material may be used to enhance the structures.

˘ T-ı˘c RE ˘ Z-e˘n-a˘ns ˘IM-ı˘j-ı˘ng): radiographic technique that uses electromagnetic resonance imaging (ma˘g-NE magnetic energy to produce multiplanar cross-sectional images of the body (see Figure 2–5E). In the digestive system, magnetic resonance imaging (MRI) is particularly useful in detecting abdominal masses and viewing images of abdominal structures. -

stool guaiac (GWI-a˘k): test performed on feces using the reagent gum guaiac to detect the presence of blood in the feces that is not apparent on visual inspection; also called Hemoccult test. ˘ G-ra˘-fe- ): imaging technique that uses high-frequency sound waves (ultraultrasonography (u ˘ l-tra˘-so˘n-O sound) that bounce off body tissues and are recorded to produce an image of an internal organ or tissue. Ultrasonic echoes are recorded and interpreted by a computer, which produces a detailed image of the organ or tissue being evaluated (see Figure 2–5B). In the digestive system, ultrasound visualization includes, but is not limited to, the liver, gallbladder, bile ducts, and pancreas. It is used to diagnose and locate cysts, tumors, and other digestive disorders and to guide the insertion of instruments during surgical procedures.

Therapeutic extracorporeal shock-wave lithotripsy (e˘ks-tra˘-kor-POR-e- -a˘l LI˘TH-o- -trı˘p-se- ): use of shock waves as a noninvasive method to destroy stones in the gallbladder and biliary ducts. Ultrasound is used to locate the stones and to monitor their destruction. After extracorporeal shock-wave lithotripsy (ESWL), a course of oral dissolution drugs is used to ensure complete removal of all stones and stone fragments. lithotripsy (LI˘TH-o- -trı˘p-se- ): procedure for eliminating a calculus in the gallbladder, renal pelvis, ureter, or bladder. Stones may be crushed surgically or by using a noninvasive method, such as hydraulic, or high-energy, shock-wave or a pulsed-dye laser. The fragments may be expelled or washed out. -

˘ S-trı˘k ˘ı n-tu- -BA-shu nasogastric intubation (na- -zo- -GA ˘ n): insertion of a nasogastric tube through the nose into the stomach. Nasogastric intubation is used to relieve gastric distention by removing gas, gastric secretions, or food.

CHAPTER 6 • DIGESTIVE SYSTEM

Medical Record Activities The two medical records included in the following activities reflect common real-life clinical scenarios to show how medical terminology is used to document patient care. The physician who specializes in the treatment of gastrointestinal disorders is a gastroenterologist; the medical specialty concerned in the diagnoses and treatment of gastrointestinal disorders is called gastroenterology. Gastroenterologists usually do not perform surgeries, but under the broad classification of surgery, they do perform such procedures as endoscopic examinations and biopsies.

✓ MEDICAL RECORD ACTIVITY 6–1. Rectal Bleeding Terminology The terms listed in the chart come from the medical record Rectal Bleeding that follows. Use a medical dictionary such as Taber’s Cyclopedic Medical Dictionary, the appendices of this book, or other resources to define each term. Then practice reading the pronunciations aloud for each term.

RECTAL BLEEDING Reading Practice pronunciation of medical terms by reading the following medical report aloud. This 50-year-old white man has lost approximately 40 pounds since his last examination. The patient says he has had no dysphagia or postprandial distress, and there is no report of diarrhea, nausea, emesis, hematemesis, or constipation. The patient has had a history of regional enteritis, appendicitis, and colonic bleeding. The regional enteritis resulted in an ileostomy with appendectomy about 6 months ago. On 5/30/XX, a sigmoidoscopy using a 10-cm scope showed no evidence of bleeding at the anorectal area. A 35-cm scope was then inserted to a level of 13 cm. At this point, angulation prevented further passage of the scope. No abnormalities had been encountered, but there was dark blood noted at that level. My impression is that the rectal bleeding could be due to a polyp, bleeding diverticulum, or rectal carcinoma.

Evaluation Review the medical record above to answer the following questions. 1. What is the patient’s symptom that made him seek medical help?

2. What surgical procedures were performed on the patient for regional enteritis?

3. What abnormality was found with the sigmoidoscopy?

CARCINOSARCOMA OF THE ESOPHAGUS Reading Practice pronunciation of medical terms by reading the following medical report aloud. ADMITTING DIAGNOSIS: Carcinosarcoma of the esophagus. DISCHARGE DIAGNOSIS: Carcinosarcoma of the esophagus. HISTORY OF PRESENT ILLNESS: Patient had been complaining of dysphagia over the last 4 months with a worsening recently in symptoms. SURGERY: Esophagoscopy was performed, and a small friable biopsy specimen was obtained. Pathology tests confirmed it to be malignant. A barium x-ray study revealed polypoid, intraluminal, esophageal obstruction. Surgical findings revealed an infiltrating tumor of the middle third of the esophagus with intraluminal, friable, polypoid masses, each 3 cm in diameter. A resection of the esophagus was performed with reanastomosis of the stomach at the aortic arch. An adjacent mediastinal lymph node was excised. There were no complications during the procedure. Patient left the OR in stable condition.

Evaluation Review the medical record above to answer the following questions. 1. What surgery was performed on this patient?

2. What diagnostic testing confirmed malignancy?

3. Where was the carcinosarcoma located?

4. Why was the adjacent lymph node excised?

7 Urinary System O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the urinary system and discuss its primary functions. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the urinary system. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio recording exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

The primary function of the urinary system is to remove waste products and other potentially harmful substances from the blood by excreting them in the urine. Organs of the urinary system are the kidneys, ureters, bladder, and urethra. The formation of urine is performed by the function of the kidneys. Other important functions of the kidneys are to regulate the body’s tissue fluid and maintain a balance of electrolytes (potassium, sodium, and calcium) and an acid-base balance in the blood. The rest of the urinary structures are responsible for storing and eliminating urine. Review Figure 7–1, which illustrates the location of urinary structures in the body.

Kidneys 7–1 Label the urinary structures in Figure 7–2 as you read the following material. The urinary system is composed of a (1) right kidney and a left kidney. These are the primary structural units of the urinary system that are responsible for the formation of urine. Each kidney is composed of an outer layer, called the (2) renal cortex, and an inner region, called the (3) renal medulla. Blood enters the kidneys through the (4) renal artery and leaves through the (5) renal vein. When inside the kidney, the renal artery branches into smaller arteries called arterioles that lead into microscopic filtering units called nephrons. Each (6) nephron is designed to filter urea and other waste products effectively from the blood. 7–2 Two combining forms that refer to the kidneys are nephr/o and ren/o. Whenever you see terms such as nephr/itis and ren/al, you will kidney(s)

Besides numerous other structures, each nephron contains a tiny ball of small, coiled, and intertwined capillaries called the (3) glomerulus (plural, glomeruli) and a (4) collecting tubule. The collecting tubule conveys the newly formed urine to the renal pelvis for excretion by the kidneys. The nephrons maintain homeostasis in the body by selectively removing waste products from the blood by forming urine, which is expelled from the body. The capsule that surrounds and encloses the glomerulus is (5) Bowman capsule.

Pathological, Diagnostic, and Therapeutic Terms The following are additional terms related to the urinary system. Recognizing and learning these terms will help you understand the connection between a pathological condition, its diagnosis, and the rationale behind the method of treatment selected for a particular disorder.

Pathological -

azoturia (a˘z-o- -TU-re- -a˘): increase of nitrogenous substances, especially urea, in urine. -

diuresis (dı--u- -RE-sı˘s): increased formation and secretion of urine. -

dysuria (dı˘s-U-re- -a˘): painful or difficult urination, symptomatic of cystitis and other urinary tract conditions. -

end-stage renal disease (RE-na˘l): final phase of a kidney disease process; disease has advanced to the point that the kidneys no longer can filter the blood adequately. -

enuresis (e˘n-u- -RE-sı˘s): involuntary discharge of urine after the age by which bladder control should have been established. In children, voluntary control of urination is usually present by age 5; also called bed-wetting at night or nocturnal enuresis. -

hypospadias (hı--po- -SPA-de- -a˘s): abnormal congenital opening of the male urethra on the undersurface of the penis. -

interstitial nephritis (ı˘n-te˘r-STI˘SH-a˘l ne˘f-RI-tı˘s): nephritis associated with pathological changes in the renal

uremia (u- -RE-me- -a˘): elevated level of urea and other nitrogenous waste products in the blood, as occurs in renal failure; also called azotemia. Wilms tumor (VI˘LMZ TOO-mo˘r): malignant neoplasm of the kidney occurring in young children, usually before age 5 years. The most frequent early signs are hypertension, a palpable mass, pain, and hematuria.

Diagnostic -

-

blood urea nitrogen (u- -RE-a˘ NI-tro- -je˘n): laboratory test that measures the amount of urea (nitrogenous waste product) normally excreted by the kidneys into the blood. An increase in the blood urea nitrogen (BUN) level may indicate impaired kidney function. ˘ G-ra˘-fe- ): radiographic technique that uses a narrow computed tomography (CT) scan (ko˘m-PU-te˘d to- -MO beam of x-rays, which rotates in a full arc around the patient to image the body in crosssectional slices. A scanner and detector send the images to a computer, which consolidates all of the data it receives from the multiple x-ray views (see Figure 2–5A). CT scanning is used to diagnose kidney, ureter, and bladder tumors, cysts, inflammation, abscesses, perforation, bleeding, and obstructions. It may be administered with or without a contrast medium. -

-

intravenous pyelogram (ı˘n-tra˘-VE-nu ˘ s PI-e˘-lo- -gra˘m): radiographic procedure in which a contrast medium is injected intravenously and serial x-ray films are taken to provide visualization of and important information about the entire urinary tract: kidneys, ureters, bladder, and urethra; also called intravenous urography (IVU) or excretory urogram or IVP. KUB: term used in a radiographic examination to determine the location, size, shape, and malformation of the kidneys, ureters, and bladder. Stones and calcified areas may be detected. -

renal scan (RE-na˘l): imaging procedure that determines renal function and shape. A radioactive substance or radiopharmaceutical that concentrates in the kidney is injected intravenously. The radioactivity is measured as it accumulates in the kidneys and is recorded as an image. This is a nuclear medicine procedure. ˘ T-ro- -gra- d pı--e˘-LO ˘ G-ra˘-fe- ): radiographic procedure in which a contrast medium retrograde pyelography (RE is introduced through a cystoscope directly into the bladder and ureters, using small-caliber catheters. Retrograde pyelography (RP) provides detailed visualization of the urinary collecting system and is useful in locating obstruction in the urinary tract. It also may be used as a substitute for an IVP when a patient is allergic to the contrast medium. ˘ L-ı˘-sı˘s): physical, chemical, and microscopic analysis of urine. urinalysis (u- -rı˘-NA ˘ G-ra˘-f e- ): radiography of the bladder and urethra after the introduction of a voiding cystourography (sı˘s-TO contrast medium and during the process of voiding urine. The bladder is filled with an opaque contrast medium before the procedure.

The physician who specializes in the treatment of urinary disorders is a urologist; the medical specialty concerned with the diagnosis and treatment of urinary disorders is urology. Because some urinary structures in the male perform a dual role, urinary functions and reproductive function (such as the urethra), the urologist also treats male reproductive disorders.

CYSTITIS Reading Practice pronunciation of medical terms by reading the following medical report aloud. This 50-year-old white woman has been complaining of diffuse pelvic pain with urinary bladder spasm since cystoscopy 10 days ago, at which time marked cystitis was noted. She reports nocturia three to four times, urinary frequency, urgency, and epigastric discomfort. The patient has had a history of polyuria, hematuria, and urinary incontinence. There is a history of numerous stones, large and small, in the gallbladder. In 19XX, she was admitted to the hospital with cholecystitis, chronic and acute; cholelithiasis; and choledocholithiasis. Subsequently, cholecystectomy, choledocholithotomy, and incidental appendectomy were performed. My impression is that the urinary incontinence is due to cystitis and is temporary in nature.

8 Reproductive Systems O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the main functions of the female and male reproductive systems. ■ Identify the organs of the female and male reproductive systems. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the female and male repro-

ductive systems. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

Although the structures of the female and male reproductive systems are different, both have a common purpose. They are specialized to produce and unite gametes (reproductive cells) and transport them to sites of fertilization. The reproductive systems of both sexes are designed specifically to perpetuate the species and pass genetic material from generation to generation. In addition, both sexes produce hormones, which are vital in the development and maintenance of sexual characteristics and the regulation of reproductive physiology. In women, the reproductive system includes the ovaries, fallopian tubes, uterus, vagina, clitoris, and vulva (see Figure 8–1). In men, the reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, ejaculatory duct, prostate, and penis. The female and the male reproductive systems are covered in this chapter.

Female Reproductive System The female reproductive system is composed of internal organs of reproduction and external genitalia. The internal organs are the ovaries, fallopian tubes (oviducts, uterine tubes), uterus, and vagina. The external organs, also called the genitalia, are known collectively as the vulva. Included in the vulva are the mons pubis, labia majora, labia minora, clitoris, and Bartholin glands (see Figure 8–1). The combined organs of the female reproductive system are designed to: produce and transport ova (female sex cells), discharge ova from the body if fertilization does not occur, and nourish and provide a place for the developing fetus throughout pregnancy if fertilization occurs. The female reproductive system also produces the female sex hormones, estrogen and progesterone, which are responsible for the development of secondary sex characteristics, such as breast development and the regulation of the menstrual cycle.

CHAPTER 8 • REPRODUCTIVE SYSTEMS

Male Reproductive System The primary sex organs of the male are called gonads, specifically the testes (singular, testis). Gonads produce gametes (sperm) and secrete sex hormones. The remaining accessory reproductive organs are the structures that are essential in caring for and transporting sperm. These structures can be divided into three categories: sperm transporting ducts, accessory glands, and copulatory organ (see Figure 8–6). Sperm-transporting ducts include the epididymis, ductus deferens, ejaculatory duct, and urethra. The accessory glands include the seminal vesicles, prostate gland, and bulbourethral glands. The copulatory organ, the penis, contains erectile tissue. All of these organs and structures are designed to accomplish the male’s reproductive role of producing and delivering sperm to the female reproductive tract, where fertilization can occur.

Medical Record Activities The following medical records reflect common real-life clinical scenarios using medical terminology to document patient care. The physician who specializes in the treatment of female reproductive disorders is a gynecologist; the medical specialty concerned with the diagnoses and treatment of female reproductive disorders is called gynecology. Obstetrics is the branch of medicine concerned with pregnancy and childbirth. It involves the care of the mother and fetus throughout pregnancy, childbirth, and postpartum (after birth). An obstetrician is a physician who specializes in obstetrics. The physician who specializes in the treatment of male reproductive and urinary tract disorders is a urologist. The medical specialty concerned with the diagnoses and treatment of male reproductive and urinary tract disorders is called urology.

✓ MEDICAL RECORD ACTIVITY 8–1. Postmenopausal Bleeding Terminology The terms listed in the chart come from the medical record Postmenopausal Bleeding that follows. Use a medical dictionary such as Taber’s Cyclopedic Medical Dictionary, the appendices of this book, or other resources to define each term.

9 Endocrine and Nervous Systems O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the endocrine system and discuss its primary functions. ■ Describe the nervous system and discuss its primary functions. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the endocrine and nervous

systems. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

The endocrine and nervous systems work together like interlocking supersystems to control many intricate activities of the body. Together they monitor changes in the body and in the external environment, interpret these changes, and coordinate appropriate responses to reestablish and maintain a relative equilibrium in the internal environment of the body (homeostasis).

Endocrine System The endocrine system comprises a network of ductless glands (see Figure 9–1), which have a rich blood supply that enables the hormones they produce to enter the bloodstream. Hormone production occurs at one site, but their effects take place at various other sites in the body. The tissues or organs that respond to the effects of a hormone are called target tissues or target organs. In contrast to the endocrine system, which slowly discharges hormones into the bloodstream, the nervous system is designed to act instantaneously by transmitting electrical impulses to specific body locations. The nervous system controls all critical body activities and reactions. It is one of the most complicated systems of the body. The nervous system coordinates voluntary (conscious) activities, such as walking, talking, and eating, and involuntary (unconscious) functions, such as reflexes to pain, body changes related to stress, and thought and emotional processes.

Hormones 9–1 Hormones are chemical substances produced by specialized cells of the body. Because they travel in the blood, hormones reach all body tissues. Only target organs contain receptors that recognize a particular hormone, however. The receptors maintain the tissue’s responsiveness to hormonal stimulation. Review Figure 9–2, which illustrates hormones of the pituitary gland and their target organs. This means the organs shown in Figure 9–2 are directly affected by the amounts of hormones released into the bloodstream by the pituitary gland. For example, an underproduction of growth hormone (GH) in children results in dwarfism.

CHAPTER 9 • ENDOCRINE AND NERVOUS SYSTEMS

Parathyroid Glands 9–39 The (3) parathyroid glands are located on the posterior surface of the thyroid gland. The parathyroid glands are so called because they are located around the thyroid gland. Label the parathyroid glands in Figure 9–3. 9–40 Usually there are two pairs of para/thyr/oid glands associated with each of the thyroid’s lobes, but the exact number varies. Nevertheless, as many as eight glands have been reported. The para/thyr/oid glands were detected accidentally. Surgeons observed that most patients who had either a partial or total thyroid/ectomy recovered uneventfully, whereas some experienced uncontrolled muscle spasms and severe pain and subsequently died. It was only after several such unexpected deaths that the parathyroid glands were discovered and their hormonal function, quite different from that of the thyroid gland hormones, became obvious.

CHAPTER 9 • ENDOCRINE AND NERVOUS SYSTEMS

Nervous System The nervous system is an extensive, intricate network of structures that activates, coordinates, and controls the functions of all other body systems and can be grouped into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and is the control center of the body. The PNS consists of the peripheral nerves, which include the cranial nerves (emerging from the base of the skull) and the spinal nerves (emerging from the spinal cord). The PNS connects the CNS to remote body parts to relay and receive messages, and its autonomic nerves regulate involuntary functions of the internal organs. Despite the complex organization of the nervous system, it consists of only two principal types of cells, neurons and neuroglia. Neurons are the basic structural and functional units of the nervous system (see Figure 9–7). They are specialized to respond to physical and chemical stimuli, conduct electrochemical impulses, and release specific chemical regulators. Through these activities, neurons perform such functions as the perception of sensory stimuli, learning, memory, and control of muscles and glands. Neuroglia do not carry impulses, but perform the functions of support and protection. Many neuroglial or glial cells form a supporting network by twining around nerve cells or lining certain structures in the brain and spinal cord. Others bind nervous tissue to supporting structures and attach the neurons to their blood vessels. Certain small glial cells are phagocytic. In other words, they protect the CNS from disease by engulfing invading microbes and clearing away debris. Neuroglia are of clinical interest because they are a common source of tumors (gliomas) of the nervous system.

PATHOLOGOCAL, DIAGNOSTIC, AND THERAPEUTIC TERMS

393

Pathological, Diagnostic, and Therapeutic Terms The following are additional terms related to the endocrine and nervous systems. Recognizing and learning these terms will help you understand the connection between a pathological condition, its diagnosis, and the rationale behind the method of treatment selected for a particular disorder.

Pathological Endocrine System ˘ -dı˘-su Addison disease (A ˘ n): relatively uncommon chronic disorder caused by deficiency of cortical hormones; results when the adrenal cortex is damaged or atrophied. Atrophy of the adrenal glands is usually the result of an autoimmune process in which circulating adrenal antibodies slowly destroy the gland. Cushing syndrome (KOOSH-ing): cluster of symptoms caused by excessive amounts of cortisol or adrenocorticotropin hormone (ACTH) circulating in the blood Most cases of Cuching syndrome are caused by administration of glucocorticoids in the treatment of immune disorders, such as asthma, rheumatoid arthritis, and lupus erythematosus. -

diabetes (dı--a˘-BE-te- z): general term that when used alone refers to diabetes mellitus, a disease that occurs in two primary forms, type 1 and type 2 diabetes, which are defined below. -

diabetes mellitus (dı--a˘-BE-te- z ME˘-lı˘-tu ˘ s): chronic metabolic disorder marked by hyperglycemia and occurs in two primary forms, type 1 diabetes and type 2 diabetes. When body cells are deprived of glucose, their principal energy fuel, they begin to metabolize fats and proteins, depositing unusually high levels of wastes in the blood causing a condition called ketosis. Hyperglycemia and ketosis are responsible for the host of troubling and commonly life-threatening symptoms of diabetes mellitus. type 1 diabetes: diabetes that is abrupt in onset and usually is diagnosed in children and young adults. It is due to the failure of the pancreas to produce insulin, making this type of disease difficult to regulate; also called insulin-dependent diabetes mellitus (IDDM). Treatment includes insulin injections to maintain a normal level of glucose in the blood. type 2 diabetes: diabetes that is gradual onset and is the most common form. It is usually diagnosed in adults older than age 40 and results from the body’s deficiency in producing enough insulin, or the body’s cells are resistant to insulin action; also called non-insulin-dependent diabetes mellitus (NIDDM). Management of this disease is less problematic than that of type 1. Treatment includes diet, weight loss, and exercise. It also may include insulin or oral antidiabetic agents, which activate the release of pancreatic insulin and improve the body’s sensitivity to insulin. ˘ L-mo˘s): abnormal protrusion of eyeball(s); may be due to thyrotoxicosis, tumor exophthalmos (e˘ks-o˘f-THA of the orbit, orbital cellulitis, leukemia, or aneurysm. -

Graves disease (GRAVZ): multisystem autoimmune disorder that involves growth of the thyroid associated with hypersecretion of thyroxine. Graves disease is characterized by an enlarged thyroid gland and exophthalmos (bulging of the eyes), which develops because of edema in the tissues of the eye sockets and swelling of the extrinsic eye muscles; also called exopthalmic goiter, thyrotoxicosis, or toxic goiter. -

insulinoma (ı˘n-su- -lı˘n-O-ma- ): tumor of the islets of Langerhans; pancreatic tumor. -

myxedema (mı˘ks-e˘-DE-ma˘): advanced hypothyroidism in adults resulting from hypofunction of the thyroid gland; affects body fluids, causing edema and increasing blood volume, increasing blood pressure.

Nervous System ˘ LTS-hı--me˘r): chronic, organic mental disorder; a form of presenile dementia caused Alzheimer disease (A by atrophy of frontal and occipital lobes. Onset is usually between age 40 and 60. Involves progressive irreversible loss of memory, deterioration of intellectual functions, apathy, speech and gait disturbances, and disorientation. Course may take from a few months to 4 or 5 years to progress to complete loss of intellectual function. ˘ S-ku- -la˘r): brain tissue damage caused by a disorder cerebrovascular accident (se˘r-e˘-bro- -VA within the blood vessels; usually due to the formation of a clot or a ruptured blood vessel; the resulting functional deficit depends on the area of the brain affected; also called apoplexy, cerebral infarction, stroke, or CVA. ˘ P-ı˘-le˘p-se- ): disorder affecting the central nervous system, characterized by recurrent seizures. epilepsy (E -

˘ N-tı˘ng-tu˘n ko- -RE-a˘): hereditary nervous disorder caused by the progressive loss of Huntington chorea (HU brain cells, leading to bizarre, involuntary, dancelike movements. ˘ F-a˘-lu hydrocephalus (hı--dro- -SE ˘ s): cranial enlargement caused by accumulation of fluid within the ventricles of the brain. -

˘ L-tı˘-pl skle˘-RO-sı˘s): progressive degenerative disease of the CNS characterized by multiple sclerosis (MU inflammation, hardening, and loss of myelin throughout the spinal cord and brain, which produces weakness and other muscular symptoms. -

neuroblastoma (nu- -ro- -bla˘s-TO-ma˘): malignant tumor composed principally of cells resembling neuroblasts; occurs chiefly in infants and children. palsy (PAWL-ze- ): partial or complete loss of motor function; paralysis. Bell: facial paralysis caused by dysfunction of a facial nerve of unknown etiology. With Bell palsy, the person may not be able to close an eye or control salivation on the affected side. The condition often results in grotesque facial disfigurement and facial spasms, but complete recovery is possible. cerebral (se˘r-e˘-bro- ): bilateral, symmetrical, nonprogressive motor dysfunction and partial paralysis usually caused by damage to the cerebrum during gestation or birth trauma but can be hereditary. ˘ R-kı˘n-su Parkinson disease (PA ˘ n): progressive, degenerative neurological disorder affecting the portion of the brain responsible for controlling movement. The unnecessary skeletal muscle movements often interfere with voluntary movement, causing the hand to shake, which is called tremor, the most common symptom of Parkinson disease. -

poliomyelitis (po- -le- -o- -mı--e˘l-I-tı˘s): inflammation of the gray matter of the spinal cord caused by a virus, often resulting in spinal and muscle deformity and paralysis. ˘ T-ı˘-ka˘): severe pain in the leg along the course of the sciatic nerve, which travels from the hip sciatica (sı--A to the foot. -

DISCHARGE DIAGNOSIS: Insulin-dependent diabetes mellitus, new onset. HISTORY OF PRESENT ILLNESS: This patient is a 15-year-old white boy who presented in the office complaining of increased appetite, polydipsia, and polyuria and was found to have elevated blood sugar of 400 and glycosuria. He was sent to the hospital for further evaluation and treatment. HOSPITAL COURSE: On admission, laboratory tests showed electrolytes WNL, and ketones were negative. Urinalysis showed a trace of sugar, BS was 380, and there was no evidence of acidosis. Metabolically the patient was stable. Patient was started on split-mixed insulin dosing. The patient and his family received full diabetic instruction during his hospitalization and seemed to understand this well. The patient picked up on all of this information quickly, asked appropriate questions, and appeared to be coping well with his new condition. By the 5th day, his polyuria and polydipsia resolved. When the patient was able to draw up and give his own insulin and perform his own fingersticks, he was discharged. DISCHARGE INSTRUCTIONS: The patient was discharged to home with parents, on a mixture of Humulin L 12 units and Humulin R 6 units each morning, with Humulin L 5 units and Humulin R 6 units each afternoon. He will continue with fingerstick BS four times daily at home until seen in the office for follow-up. I warned him of all glycemic symptoms to watch for, and he is to call the office with any problems that may occur. He is to follow an ADA 2000-calorie diet. DISCHARGE CONDITION: The patient’s overall condition was much improved, and at the time of discharge BS levels were stabilized and he was doing well.

Evaluation Review the medical record to answer the following questions. 1. What symptoms of DM did the patient experience before his office visit?

2. What confirmed the patient’s new diagnosis of DM?

3. What conditions had to be met before the patient could be discharged from the hospital?

CHAPTER 9 • ENDOCRINE AND NERVOUS SYSTEMS

CEREBROVASCULAR ACCIDENT Reading Practice pronunciation of medical terms by reading the following medical report aloud. The patient is a moderately obese white woman who was admitted to Riverside Hospital because of a sudden episode of CVA. She recalls an episode of vertigo 3 days ago. The patient is being nursed at home by her daughter because of terminal adenocarcinoma of the head of the pancreas with metastasis to the liver, which was diagnosed in December. About 5 hours before the CVA, the patient fell to the floor with paralysis of the right arm and right leg and aphasia. She has not noticed any difficulty with deglutition. Apparently with the onset of the CVA attack she also experienced diplopia. She denies any difficulty with her cardiovascular system in the past. The patient was in the hospital 5 years ago because of generalized biliary-type disease with jaundice, pruritus, weight loss, and anorexia. Subsequently, she was seen in consultation, and cholecystojejunostomy and jejunojejunostomy was performed. Dx: (1) CVA, probably secondary to metastatic lesion of the brain or cerebrovascular disease; (2) evidence of the previously described deterioration secondary to carcinoma of the pancreas with metastases of the liver.

Evaluation Review the medical record to answer the following questions. 1. Did the patient have a history of cardiovascular problems before her CVA?

2. What symptoms did the patient experience just before her CVA?

3. What is the primary site of this patient’s cancer?

4. What is cerebrovascular disease?

5. What is the probable cause of the patient’s CVA?

tem. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

Skeletal System The musculoskeletal system is composed of bones, joints, and muscles. The skeletal system of a human adult consists of 206 individual bones, but only the major bones are covered in this chapter. For anatomical purposes, the human skeleton is divided into the axial skeleton (distinguished with bone color in Figure 10–1) and the appendicular skeleton (distinguished with blue color in Figure 10–1). The axial skeleton protects internal organs and provides central support for the body, and the appendicular skeleton enables the body to move. The ability to walk, run, or catch a ball is possible due to the movable joints of the limbs. The main function of bones is to form a skeleton to support and protect the body and serve as storage areas for mineral salts, especially calcium and phosphorus. Joints are the places where two bones articulate, or connect. Because bones cannot move without the help of muscles, contraction must be provided by muscular tissue.

/

.

10–2 There are four principal types of bones—long bones, short bones, flat bones, and irregular bones. The long bones of the extremities are the strongest bones of the arms and legs. The cube-shaped short bones include the bones of the ankles, wrists, and toes. Flat bones are the broad bones found in the skull, shoulder, and ribs. Irregular bones have varied shapes and sizes and are often clustered, such as the bones of the vertebrae and certain bones of the ears and face.

CHAPTER 10 • MUSCULOSKELETAL SYSTEM

10–4 The two ends of bones, the (5) distal epiphysis and (6) proximal epiphysis, have a bulbous shape to provide space for muscle and ligament attachments near the joints. Label these structures in Figure 10–2. 10–5 There are two kinds of bone tissue, based on porosity, and most bones have both types. Compact (dense) bone tissue is the hard, outer layer; spongy (cancellous) bone tissue is the porous, highly vascular inner portion. Compact bone tissue is covered by periosteum that serves for attachment of muscles, provides protection, and gives durable strength to the bone. The (7) spongy bone tissue makes the bone lighter and provides a space for bone marrow where blood cells are produced. Label the spongy bone in Figure 10–2, and note the position and structure of compact and spongy bone. 10–6 In Figure 10–2, observe how the diaphysis forms a cylinder that surrounds the medullary cavity. In adults, the medullary cavity contains fat yellow marrow, so named because of the large amounts of fat it contains. 10–7 The peri/oste/um, as illustrated in Figure 10–2, covers the entire surface of the bone. Its blood vessels supply nutrients, and its nerves signal pain. In growing bones, the inner layer contains the bone-forming cells known as oste/o/blasts. Because blood vessels and oste/o/blasts are located here, the peri/oste/um provides a means for bone repair and general bone nutrition. Bones that lose peri/oste/um through injury or disease usually scale or die. As discussed earlier, the peri/oste/um also provides a point of attachment for muscles.

CHAPTER 10 • MUSCULOSKELETAL SYSTEM

Joints 10–35 To allow for body movements, bones must have points where they meet (articulate). These articulating points form joints that have various degrees of mobility. Some are freely movable (diarthroses), others are only slightly movable (amphiarthroses), and the remaining are totally immovable (synarthroses). All three types are necessary for smooth, coordinated body movements.

CHAPTER 10 • MUSCULOSKELETAL SYSTEM

(1) crani/o refers to the cranium (skull). (2) stern/o refers to the sternum (breastbone). (3) cost/o refers to the ribs, which are attached to the sternum. (4) vertebr/o refers to the vertebrae (backbone). The vertebral column also is called the spinal column and is composed of 26 bones called vertebr/ae (singular, vertebra). (5) humer/o refers to the humerus (upper arm bone). The humerus articulates with the scapula at the shoulder and with the radius and ulna at the elbow. (6) carp/o refers to the carpus (wrist bones). There are eight wrist bones. (7) metacarp/o refers to the metacarpus (hand bones). The metacarpals (plural) radiate from the wristlike spokes and form the palm of the hand. (8) phalang/o refers to the phalanges (bones of fingers and toes). (9) pelv/i and pelv/o refer to the pelvis. The pelvis, also called the pelvic girdle, is composed of three pairs of fused bones (the ilium, pubis, and ischium), the sacrum, and the coccyx. The pelvis provides attachment for the legs and supports the soft organs of the abdominal cavity (see Figure 10–1). (10) femor/o refers to the femur (thigh bone). The femur is the longest and strongest bone in the body. It articulates with the hip bone and the bones of the lower leg. (11) patell/o refers to the patella (kneecap). The patella articulates with the femur, but essentially is a floating bone. The main function of this bone is to protect the knee joint, but its exposed position makes it vulnerable to dislocation and fracture. (12) tibi/o refers to the tibia (larger inner bone of lower leg). The tibia is the weight-bearing bone of the lower leg. (13) fibul/o refers to the fibula (smaller, outer bone of lower leg). The fibula is not a weight-bearing bone but is important because muscles are attached and anchored to it. (14) calcane/o refers to the calcaneum (heel bone).

Fractures and Repairs 10–55 A fracture is a break or crack in the bone. Fractures are defined according to the type and extent of the break. A (1) closed fracture means the bone is broken with no open wound; surrounding tissue damage is minimal. An (2) open fracture, also called compound fracture, means the broken end of a bone pierces the skin creating an open wound. There may be extensive damage to surrounding blood vessels, nerves, and muscles. Label the closed and open fractures in Figure 10–4.

10–56 Discussion of examples of different types of fractures follows. A (3) greenstick fracture means there is an incomplete break of a soft bone; the bone is partially bent and partially broken. These fractures usually occur in children because their bones tend to splinter rather than break completely. A (4) comminuted fracture occurs when the bone is broken into pieces. In an (5) impacted fracture, the broken ends of a bone are forced into one another; many bone fragments may be created by such a fracture. A (6) complicated fracture involves extensive soft tissue injury, such as when a broken rib pierces a lung. A (7) Colles fracture is a break of the lower end of the radius, which occurs just above the wrist. It causes displacement of the hand and usually occurs as a result of flexing a hand to cushion a fall. An (8) incomplete fracture is when the line of fracture does not include the whole bone. Label and study the different types of fractures in Figure 10–4.

MUSCULAR SYSTEM

435

Muscular System The human body is composed of hundreds of skeletal muscles, overlapping each in intricate layers. Muscles usually are described in groups according to their anatomical location and cooperative function. Selected muscles of the body are illustrated in Figure 10–6. All muscles, through contraction, provide the body with motion or body posture. The less apparent motions provided by muscles include the passage and elimination of food through the digestive system, propulsion of blood through the arteries, and contraction of the bladder to eliminate urine. In addition, muscles function in body movements in several different ways to allow a range of motion for the contraction and relaxation of muscle fibers. Biceps brachii

Anteroposterior and lateral views of the lumbar spine and an AP view of the sacrum show a placement of L5 on S1. The L5 to S1 intervertebral disk space contains a slight shadow of decreased density. There is now slight narrowing of the L3 to L4 and L4 to L5 spaces. Bilateral laminectomies appear to have been done at L5 to S1. Slight hypertrophic lipping of the upper lumbar vertebral bodies is now seen, as is slight lipping of the upper margin of the body of L4. The sacroiliac joint spaces are well preserved. Lateral views of the lumbosacral spine taken with the spine in flexion and extension show slight motion at all of the lumbar and lumbosacral levels. IMPRESSION: 1. Degenerative, intervertebral disk disease at L5 to S1, now also accompanied by slight narrowing of the L3 to L4 and L4 to L5 disk spaces. 2. Slight motion at all of the lumbar and lumbosacral levels.

ROTATOR CUFF TEAR, RIGHT SHOULDER Reading Practice pronunciation of medical terms by reading the following medical report aloud. PREOPERATIVE AND POSTOPERATIVE DIAGNOSIS: Rotator cuff tear, right shoulder. Degenerative arthritis, right acromioclavicular joint. Calcific tendinitis at the level of the superior glenoid tuberosity, right shoulder. Early degenerative osteoarthritis of the right shoulder. History of gouty arthritis. OPERATION: Open repair of rotator cuff, open incision outer end of clavicle, anterior acromioplasty, glenohumeral and subacromial arthroscopy with arthroscopic bursectomy. FINDINGS: A glenohumeral arthroscopy revealed the superior, anterior, inferior, and posterior glenoid labra were intact. There was some fraying of the anterior glenoid labrum. The long head of the biceps was intact. We were unable to visualize any intra-articular calcification. We observed the takeoff of the long head of the biceps from the posterior superior edge of the glenoid labrum and the glenoid tuberosity. There was an osteophyte inferiorly on the humeral head. There was a deep surface tear of the rotator cuff at the posterior superior corner of the greater tuberosity of the humerus at the infraspinatus insertion. There was an extremely dense subacromial bursal scar. There was prominence of the inferior edge of the AC joint, with inferior AC joint and anterior acromial spurs.

11 Special Senses: The Eyes and Ears O B J E C T I V E S Upon completion of this chapter, you will be able to: ■ Describe the sensory organs of seeing and hearing and explain their primary functions. ■ Identify the major structures of the eyes and ears. ■ Describe pathological, diagnostic, therapeutic, and other terms related to the sensory organs of see-

ing and hearing. ■ Recognize, define, pronounce, and spell terms correctly by completing the audio CD-ROM exercises. ■ Demonstrate your knowledge of this chapter by successfully completing the frames, reviews, and

medical report evaluations.

The major senses of the body are sight, hearing, smell, taste, touch, and balance. These sensations are identified with specific body organs. The senses of smell and taste were discussed in previous chapters; the senses of sight, hearing, and balance are discussed in this chapter. Other senses of the body not attributed to any specific organ include hunger, thirst, pain, and temperature. This chapter provides information about the eyes and ears.

Eye The eyes and their accessory structures are the receptor organs that provide vision. As one of the most important sense organs of the body, the eyes provide us not only with most of the information about what we see, but also of what we learn from printed material. Similar to other sensory organs, the eyes are constructed to detect stimuli in the environment and to transmit those observations to the brain for visual interpretation.

11–1 The eye is a globe-shaped, hollow structure set within a bony cavity. The bony cavity, or orbit, houses the eyeball and associated structures, such as the eye muscles, nerves, and blood vessels. Most of the eyeball is protected from trauma by the orbit’s bony cavity. The wall of the eyeball is composed of three layers: the (1) sclera, the white outer layer of the eyeball, is composed of fibrous connective tissue. On the most anterior portion of the eye, the sclera forms a transparent, domed structure called the (2) cornea. The cornea also protects the front part of the eye from injury and is the first part of the eye that refracts light rays. In addition, the cornea is avascular (without blood vessels or capillaries), but is well supplied with nerve endings, most of which are pain fibers. For this reason, some people can never adjust to wearing contact lenses. Label the structures in Figure 11–1 as you observe the location and layers of the eyeball.

11–2 The (3) choroid layer lies below the sclera. It contains blood vessels and a dark pigmented tissue that prevents glare within the eyeball by absorbing light. The anterior portion of the choroid is modified and forms the (4) ciliary body (or muscle) and the (5) iris, the colored portion of the eye. The (6) retina lines the posterior two thirds portion of the eyeball and contains rods and cones, the sensory receptors for vision. Rods perceive only the presence of light, whereas cones perceive the different wavelengths of light as colors. The primary function of the retina is image formation. Continue to label the structures in Figure 11–1 as you observe the location and layers of the eyeball. 11–3 The combining form scler/o refers to hardening; sclera (white of eye); choroid/o refers to the choroid; and retin/o refers to the retina.

11–10 The opening in the center of the iris is called the (7) pupil. The amount of light entering the eye is controlled by contractions and dilations of the pupil.

11–11 The sensory receptors of vision, the rods and cones, contain light-sensitive molecules (photopigments) that convert light energy into electrical impulses. Impulses generated by the rods and cones are transmitted by retinal nerve fibers to areas of the brain that are responsible for processing visual information. The retinal nerve fibers unite at the (8) optic disk and cut across through the wall of the eyeball as the (9) optic nerve. Because the optic disk has no rods or cones, it is known as the blind spot. Label the structures in Figure 11–1 as you learn about the location and role these structures play in providing vision.

Ear The ears and their accessory structures are the receptor organs that enable us to hear and to maintain our balance. Each ear consists of three divisions—the external ear, the middle ear, and the inner ear. The external and middle ear conduct sound waves through the ear; the inner ear contains auditory structures that receive the sound waves and transmits them to the brain for interpretation. The inner ear also contains specialized receptors that maintain balance and equilibrium regardless of changes in body position or motion.

RETINAL DETACHMENT Reading Practice pronunciation of medical terms by reading the following medical report aloud. DIAGNOSIS: Total retinal detachment, left eye, secondary to complications of retinitis. PROCEDURE: The patient was taken to the operating room, placed on the operating table, IV line begun, EKG lead monitor attached, and retrobulbar anesthetic given, achieving good anesthesia and akinesia. The patient was scrubbed, prepped, and draped in a standard sterile fashion for retinal surgery. A 360-degree conjunctival opening was made and 2–0 silk sutures were placed around each rectus muscle. Four millimeters from the limbus, a mark in the sclera was made and preplaced 5–0 Mersiline suture was passed; MVR stab incision made, and 4-mm infusion cannula was slipped into position and visualized inside the eye. Similar sclerotomy sites were made superior nasally and superior temporally. Trans pars plana vitrectomy was undertaken. Dense vitreous hemorrhage and debris were found, which were removed. There was incomplete posterior vitreous attachment. The retina was almost totally detached, and a small amount of nasal retina was still attached. A linear retinal break was seen just above the disk along a vessel. Gradually all the peripheral vitreous was removed. The air-fluid exchange was performed with some difficulty because some sort of vitreous was found anteriorly, which loculated the bubble. It gave me a peculiar view, but slowly the retina became totally flat, and we treated the retinal break with the diode laser. A 240 band was wrapped around the eye and fixed with the Watke’s sleeve superior temporally. The sclerotomies were all sewn closed. Before the last sclerotomy was closed, the air was exchanged for silicone. The eye was left soft because the patient had poor perfusion.

Evaluation Review the medical record above to answer the following questions. 1. Where is the retina located?

2. Was the anesthetic administered behind or in front of the eyeball?

estrogen hormone: agent used in estrogen replacement therapy (ERT) during menopause to correct estrogen deficiency and as chemotherapy for some types of cancer, including tumors of the prostate. expectorant: agent that promotes the expulsion of mucus from the respiratory tract. fibrinolytic: agent that triggers the body to produce plasmin, an enzyme that dissolves clots; used to treat acute pulmonary embolism and, occasionally, deep vein thromboses. gold therapy, chrysotherapy: therapy that uses gold compounds as a medicine; employed in treating rheumatoid arthritis. gonadotropin: agent used to raise sperm count in infertility cases. hemostatic: any drug, medicine, or blood component that serves to stop bleeding. hypnotic: substance that induces sleep or hypnosis. inotropic, cardiotonic: drugs that affect the force of contraction of the heart; used to treat cardiac arrhythmias and cardiac failure. insulin: synthetic form of the insulin hormone for diabetes administered by injection to lower the glucose (sugar) level in the blood. keratolytic: agent used to destroy and soften the outer layer of skin so that it is sloughed off or shed. Strong keratolytics are effective for removing warts and corns. Milder preparations are used to promote the shedding of scales and crusts in eczema, psoriasis, and seborrheic dermatitis. Weak keratolytics irritate inflamed skin, acting as tonics that speed up the healing process. laxative (cathartic, purgative): agent that promotes bowel movements or defecation or both. When used in smaller doses, it relieves constipation. When used in larger doses, it evacuates the entire gasrointestinal tract, for example, before surgery or intestinal radiologic examinations. miotic: any substance that constricts the pupil of the eye. These agents are used in the treatment of glaucoma. mucolytic: group of agents that liquefy sputum or reduce its viscosity so that it can be coughed up more easily. mydriatic: topical drug used to dilate the pupil and paralyze the muscles of accommodation of the iris; used to prepare the eye for internal examination and to treat inflammatory conditions of the iris. nitrate: class of drugs used to treat angina. opiate: narcotic drug that contains opium or its derivatives. Opiates are sometimes used for relieving severe pain. oral contraceptive: pharmaceutically prepared chemical that is quite similar to natural hormones and act by preventing ovulation. When taken according to instructions, oral contraceptives are almost 100% effective; also called “the pill.” oxytocin: pharmaceutically prepared chemical that is similar to the pituitary hormone oxytocin. This hormone stimulates the uterus to contract, inducing labor, or to rid the uterus of an unexpelled placenta or a fetus that has died. parasiticide: agent that, in its oral form, kills systemic parasites, such as pinworm or tapeworm.

APPENDIX D • DRUG CLASSIFICATIONS

protective: agent that functions by covering, cooling, drying, or soothing inflamed skin. Protectives do not penetrate or soften the skin but form a long-lasting film that protects the skin from air, water, and clothing during the natural healing process. psychotropic: drug that affects and can alter psychic function, behavior, or experience. Psychotropics are often employed in the management of psychotic disorders. relaxant: drug that reduces tension, such as a muscle relaxant or bowel relaxant. sedative: agent that exerts a calming or tranquilizing effect. spermicidal: substance that destroys sperm and is used within the woman’s vagina for contraceptive purposes. Spermicidals consist of jellies, creams, and foams and do not require a prescription. topical anesthetic: agent that is prescribed for pain on skin surfaces or mucous membranes that is caused by wounds, hemorrhoids, or sunburns. Topical anesthetics relieve pain and itching by numbing the skin layers and mucous membranes. They are applied directly by means of sprays, creams, gargles, suppositories, and other preparations; also used to numb the skin to make the injection of medication more comfortable. tranquilizer: drug used to calm anxious or agitated people, ideally without decreasing their consciousness. uricosuric: drug that increases the urinary excretion of uric acid, reducing the concentration of uric acid in the blood; used in the treatment of gout. vasoconstrictor: drug that causes a narrowing of blood vessels; used to decrease blood flow. vasodilator: drug that expands blood vessels; used in the treatment of angina pectoris and hypertension.

G Spanish Translations Introduction The purpose of this appendix is to provide guidelines to help health-care practitioners identify and pronounce Spanish terms commonly used in the various medical specialties. Although the spelling of some Spanish terms resembles English terms, the terms are still pronounced with a Spanish accent. Because of these similarities, it is easier to learn the meaning and pronunciations of Spanish words. The first step in communicating with Spanish-speaking patients is to learn the Spanish sound system. The Spanish Sounds section that follows provides Spanish pronunciations of vowels and consonants. Practice the pronunciations in the Spanish Sounds table, and use the table as a reference when you review Spanish pronunciations in the Chapter Tables section.

Spanish Sounds The following table lists vowels and their Spanish pronunciations. Practice the pronunciations before continuing with the other information in this appendix.

Chapter Tables Many Spanish terms ending in the letter “a” denote the feminine gender of the noun being modified, as in izquierda; many Spanish terms ending in the letter “o” denote masculine gender of the noun being modified, as in izquierdo. These types of Spanish terms in this section are clearly identified. In summary, to change the feminine gender of the noun the adjective modifies, change the ending letter “a” (female) to “o” (male), as in the terms izquierda (female), izquierdo (male). In the following tables, capitalization is used to indicate primary accent of Spanish words. The capital letters indicate that emphasis is placed on the respective syllable when pronouncing the Spanish word. For example, the pronunciation of an-te-re-OR indicates emphasis on the last syllable.
